Nancy Solomon of New Jersey Public Radio and WNYC is on the scene, and says she can see 20 to 30 people who are injured. At least four of the injured are unable to walk, she says.

"I got off my train on the way into work, and as I was walking through the station we could see that a train had come through the place where it's supposed to stop, all the way into the station — not into the waiting room but into the outdoor part where people transfer," she tells our Newscast unit.

"About a fourth of the roof is collapsed," she says, and water was spraying from the damaged station.

It's unclear if there are any fatalities, she says.
